Additional seasons of legal series Suits will also air on Dave as part of the new pact.

"Do No Harm's exciting new twist on the Jekyll and Hyde story is original and out of the ordinary, making it a perfect fit for Watch and the ideal companion to established US drama Grimm, which continues to attract a large audience," said UKTV's controller Emma Tennant.

"Suits has also been a huge breakout hit for us on Dave, proving that US drama can work on the channel and we are delighted to have secured future seasons for our UK viewers."
